This is the same reason I roll my eyes when a ride sharing app asks me to rate a driver - I assume anything less than 5 stars is going to kill their work so I just give 5 stars. The one time I had a bad experience (nice driver, liked to talk, but could not drive and talk and almost got us killed), I just skipped the review entirely.
I have this working theory that we (people privileged enough to spend lots of time per day on the Internet) are getting close to being able to spend our time in fictional spaces; one of the reasons for that is the fact we spend a lot of goddamn time lying about things in order to make systems work the way we want. Now let's you and I sit down and talk about what 4 stars in iTunes/ Spotify/ whatever means in your personal system . . .
